Nunez through the middle
Nunez spent much of Benfica's season playing as a centre-forward, and with Sadio Mane pushing for an exit this summer, it's likely that the incoming 22-year-old would play there for Liverpool.
At 6ft2, Nunez would be Klopp's tallest starting centre-forward since Lucas Barrios in his Bundesliga-winning Borussia Dortmund sides. However, his energy and pace make him compatible with the German's typical forward options.
Trent Alexander-Arnold and Andy Robertson are two of the greatest crossers in world football (the former perhaps of all time), and having a taller target to aim for will surely be of benefit.
Mohamed Salah and Diaz could benefit from a physical presence drawing bodies away, making it easier to create a yard of separation from their defender.
Possible trios:
Salah (RW) - Nunez (CF) - Diaz (LW)
Salah (RW) - Nunez (CF) - Jota (LW)
Salah (RW) - Nunez (CF) - Mane (LW)
Nunez out wide
Despite mainly playing through the middle, Nunez has plenty of experience starting from the left flank.
Diaz has nailed down the left-wing role since his arrival from Porto, but if Klopp fancies shaking things up then he could always play another of the Primeira Liga's finest out there instead.
Nunez isn't as technically gifted as Diaz so he would likely struggle at times when the game is slowed down, but his searing pace would make him a useful wide option in transition.
Possible trios:
Salah (RW) - Jota (CF) - Nunez (LW)
Salah (RW) - Mane (CF) - Nunez (LW)
Salah (RW) - Firmino (CF) - Nunez (LW)
Diaz (RW) - Salah (CF) - Nunez (LW)
Nunez off the bench?
Theoretically, this should only be an option for a few weeks while Nunez adjusts to Premier League life.
But if he doesn't hit the ground running then Klopp still has a wealth of options in his squad and bringing the Uruguayan off the bench is a terrifying prospect for opponents to adjust to.
Moreover, Liverpool might not sell Mane and could stick with the rotations they used up top for the 2021/22 season. You never know in football.
